Drive Axle CV Boot replacement

[NickW]

For replacing the CV boots everyone refers to the artilce at http://toyotasurf.asn.au/techsite/cvjoints.htm - has anyone completed this task?

The procedure of removing the axle sumarised seems to be:
1. loosen wheel nuts and jack up the front wheel
2. remove the six nuts and bolts attaching the half axle to the diff
3. remove wheel nuts and tyre
4. remove cap on end of axle
5. Remove small bolt with 12mm spanner and remove 6 dome nuts holding hub on and washers.
6. remove hub using 2 H/T 8mm bolts and screwing them in
7. remove a circlip and washer (behind hub)
8. remove axle by sliding it towards the universal joint on the back of the axle

My Surf has switchable 4WD so I assume it has 'automatic locking hubs'; it's a 1990 2.4TD SSR. In the Haynes manual for Hi-Lux & 4Runner the task looks a lot more complicated, it talks about removing the freewheeling hub (section 21). Also the garage seemed to want to make a big job of it when describing the work involved. Just hoping to talk to someone with some first hand experience.

it's an easy job but it takes about 3-4 hours to complete

At task no.8 above, do you slide the axle outwards towards the wheel's brake disc and withdraw it through the centre of the brake disc, whilst collecting the half axle casing underneath and on the inboard side of the wheel?

Axle goes inwards. The CVs will not fit through the steering Knuckle.

I imagine the axle slots into the differential, surely that has to be drawn outwards first before the section of casing (part with 6 bolts) can be moved sideways/down and removed?

Its easy, the inner shaft ends bolts to diff flange, so you just unbolt it, drop it through the wishbone, and pull the stub axle from the hub. Its obvious if have a look under the truck.

You also don't have any hubs, just drive plates, unbolt them, remove the circlip and the shaft will slide out.

You need to jack under the wishbone to get them parallel to the floor, or there won't be enough space to clear the bolts on the diff flange.

Are the bolts in the diff flange fixed/welded in? I've not managed to shift the nuts yet, think I will have to apply some heat.

The bolts are held in place by splines. They can be knocked out if needed.

Make sure the truck is securely supported, 'cos those nuts are feckin' tight, at least nine grunts tight. (wheel nuts are about three grunts by comparison)

That's a good article, very useful thanks.

In the 4Runner manual there are some torque settings but it's not obvious which one applies to the half axle connecting to the diff flange, or if it is actually listed. Has anyone got the correct torque settings for these nuts?

To add to this and when in few years time I search again I will remember.

On my LN107 (pickup) I needed to slacken off the torsion bar (40 turns) and get a fat bloke to add weight to the front of the truck to get the wishbone anywhere near parallel and remove the shock lower bolt / move shock out of the way.

Just curious but this circlip and washer that keeps getting mentioned. What does it actually hold? Because as I understand it, the 6 dome bolts hold the drive plate on, the 12mm bolt holds the end of the CV joint in, and the 54mm(?) holds the bearing assembly onto the hub.

Was just wondering as on my truck, the drivers side outer CV joint (not the shaft) can be moved in and out by hand a few mm. This I think is whats causing the screech when on RH lock.

DM a little play is normal if its to much shims are available.

It's the circlip that holds the driveshaft in place, the 12mm bolt is only there to stop the driveshaft coming adrift if the circlip breaks.

Aha! Cheers for the help guys. I'll check it tomorrow and almost positive I'll find the circlip has failed/fallen off/was forgotten about
